Commissioning

When the hob has been fully installed it will be necessary

to check the minimum flame setting. To do this, follow

the procedure below.

- Turn the gas tap to the MAX position and ignite.

- Set the gas tap to the MIN flame position then turn

the control knob from MIN to MAX several times. If

the flame is unstable or is extinguished follow the

procedure below.

Procedure:

Re-ignite the burner and set to MIN.

Remove the control knob.

To adjust, use a thin bladed screwdriver and turn

the adjustment screw (see diagram) until the flame

is steady and does not extinguish, when the knob

is turned from MIN to MAX. Repeat this procedure

for all burners.

Pressure Testing

Remove left hand pan support and front left burner

cap and crown.
Fit manometer tube over the injector.
Turn on the burner gas supply and ignite another

burner.
The pressure reading should be nominally 20mbar

and must be between 17 mbar and 25mbar.
Turn off the burner supplies.

Conversion from Natural Gas to

LPG

It is important to note that this model is designed for use

with natural gas but can be converted for use with butane

or propane gas providing the correct injectors are fitted.

The gas rate is adjusted to suit.

Method

• Ensure that the gas taps are in the 'OFF' position

• Isolate the hob from the electrical supply

• Remove all pan supports, burner caps, rings, crowns

and control knobs.

• With the aid of a 7mm box spanner the burner injectors

can  then  be  unscrewed  and  replaced  by  the

appropriate LPG injectors.

TO ADJUST THE GAS RATE

With the aid of a thin bladed screwdriver completely

tighten down the by pass adjustment screw, which is

located down the centre of the gas tap control shaft.

Upon completion stick the replacement rating plate on

the under side of the hob.

IMPORTANT
The replacement/conversion of the gas hob

should only be undertaken by a competent

person.
